I think ELN won't have this problem (at large scale) because it will inherit
sources from Fedora where any new Fedora build has a bumped release for the
reason you described. It will resemble more a shadow Koji for the secondary
architectures.
But you are right that funny times can come when an ELN build screws things and
ELN people will have to not only untag it but also delete it from the NVR index so
that it can be rebuilt again with the same NVR. Fedora people weren't happy if
they had to add a dummy release bumps just only because of ELN.

I think they will just throw it away and start from the scratch. At the end
they would like to rebuild all the packages with the new configuration.
